Steam provides an easy method to allow you to verify the integrity of your Train Simulator or Train Sim World installation. This process will check for any corrupted and/or missing files that are required to properly run the software. This process will also check any add-on content you have purchased.

Please follow the instructions below to perform a file verification. After this is complete, any missing files will automatically be re-downloaded. If you’ve been encountering a problem before the file verification, please attempt to reproduce the issue after the process is complete, to see if it has fixed the issue.

Before you begin, it’s important that:

You perform this overnight or when you’re not using your computer as the process can take a long time, particularly if you own several items of add-on content (DLC). We would recommend you allow at least 12 hours for this.

You allow the process to fully complete, do not interrupt, close Steam or restart your computer until you’re satisfied it has finished.

You understand that any modifications or third-party content (that were not downloaded from Steam) will be removed by performing this process.

Load Steam and navigate to your Game Library

Right-click once on Train Simulator or Train Sim World and select Properties

Select the Local Files tab and left-click on Verify Integrity of Game Files

Allow the process to complete and allow Steam to download any files that need to be reacquired

Once completed, it’s important that you restart Steam by selecting Exit from the Steam

Note it may also be necessary for you to restart your computer. If you continue to experience issues with Steam, Train Simulator and/or Train Sim World, please try restarting your computer.
